I buy a product called Knorr TasteBreaks. It is a powdered soup in a plastic cup. I remove the powder to carry and recycle the plastic cup. The one that I have now is Split Pea with a net weight of 1.5 oz. It is a little high on sodium, so I often cut it down with dehydrated Quinoa or instant rice.

I purchased this one from World Market for 99 cents for the individual serving.

Thanks, Bob and Sarah. I hadn't thought of looking for soup in the cups. I will definitely dump the cups if I can find what I'm looking for. I used to get dehydrated tomato soup in pouches in Norway all the time, but that was decades ago. Mayonnaise came in tubes like toothpaste, too.
